BELT-SHIPPER.

SPECIFICATION forming part of Letters Patent No. 244,336, dated July 12,1881.

Application filed June 20, 1881. (No model.) I

To all whom it may concern Be it known that I, STEPHEN STRUNZ, a citizenof the United States, residing at Pittsburg, in the county of Alleghenyand State of Pennsylvania, have invented new and useful Improvements inBelt-Shippers, of which the following is a specification.

The object of this invention is to provide a belt-shipper which can bereadily operated from any desired point, either adjacent to or at aconsiderable distance from the shipper also, to construct the shipper sothat several belts can be shipped by the same mechanism, and also toconstruct the same so that when the belt is on the loose pulley theshaking of the machine can at no time cause the belt to be accidentallyshipped from the loose to the fast pulley, so as to start the machinethat is to be driven by belt-power.

To such end my invention consists in a shipper consisting of a jointedbar comprising three hinged sections, one end or outer'section beingpivoted, and the other end or outer section being arranged to slidethrough guides and to ship the belt when moved endwise, a rope or cordbeing attached to one end of the central section of the jointed bar andpassed over pulleys to some desired pointfrom which the shipper is to beoperated, as hereinafter described.

In the drawings, Figure l is a side elevation of my invention with thedrivin g-belt upon the loose pulley, and Fig. 2 is a like view with thebelt upon the fast pulley.

My invention can be applied to all classes of machines where the belt isto be shipped from a fast to a loose pulley, or vice versa, although Iespecially intend it for presses Which occupy considerable space, andwhich therefore render it desirable for the operator to be able to shipthe belt from some particular locality in the room where the apparatusis placed.

The shipper is composed of a jointed bar divided into three sections, AA A the two end sections thereof being connected with the centralsection by means of the hinges B B, the former of which is secured tothe upper sides of one of the end sections and the central section,while the latter hinge has its leaves secured to the under sides of thecenter and the remaining end section of this jointed shipper-bar. Thesection A of the said jointed bar is pivoted atits outer end to asuitable bar or beam, 0, while the remaining end section, A, is arrangedto pass through the straps or guides D, which can be secured either tothe bar 0, or to any other suitable rigid support.

E indicates the loose pulley, and F the fast pulley, both of which aremounted upon a shaft, as usual.

The driving-belt G, which is to be shifted from one pulley to another,passes through a bail, H, which is secured to the sliding end section A,whereby an endwise movement of the said section will shift the belt. Asa means for enabling a person to operate this belt-shipper from anydesired locality, I connect a cord or rope, I, with the central sectionof the jointed bar at a point adjacent to its end that is hinged to theswinging end section of the jointed bar, and I extend this cord up overa suitable pulley, K, from which it can be carried over as many otherpulleys as desired and then brought down to within convenient reach ofthe operator. Now, the belt being upon the outer loose pulley, E, thesections of the jointed bar will lie at a right line with their squareends abutting against each other, so as to practically constitute onesolid bar. This absolutely prevents any accidental shifting of the beltwhen the bar is thus straightened out.

In order to ship the belt from the loose to the fast pulley, to transmitmotion from the belt to the main shaft of the machine, the operator needonly draw upon the end of the rope or cord that is within reach, wherebythe tension on the same will elevate the connected ends of the sectionsA A of the jointed bar, raising the connected ends thereof laterallyfrom the line of the sliding section A, whereby the latter will be drawnback, and thereby ship the belt. As soon, however, as the cord isreleased the weight of the central section and the pivoted swingingsection will cause their connected ends to drop, whereby they willstraighten out, and hence throw the sliding bar forward, the latter, inits movement, shipping the belt from the fast to the loose pulley.

It will be evident that the sliding section A of the jointed bar couldbe extended so as to carry another bail, and hence serve to shift asecond belt passing through the same.

The device is extremely simple, not liable to get out of repair, and,owing to the few parts employed, it can be made at small cost.

Having thus described my invention, what I claim is- 1. A belt-shipperconsisting of a jointed bar passing through the said guides, andprovided with a bail passing around the belt, a central section, A,hinged to the sliding section at one end by a hinge on their top sides,and

hinged at its remaining end to a pivoted section, A, by a hinge on theunder sides of said sections, the device being adapted to be operated bya rope or cord which is passed over a pulley, substantially asdescribed.

In testimony whereof Ihavehereunto set my hand in the presence of twosubscribing witnesses.
